Frieda Klein is back. She's a psychotherapist tasked with assessing Hannah Docherty who has been imprisoned in a psychiatric hospital after being charged with the murder of her mother, stepfather, and brother. Hannah's ten year incarceration has been filled with physical abuse from other patients as well as mental anguish from long bouts of solitary confinement. Frieda has her doubts about the case especially when a likewise skeptical blogger winds up dead. Adding another layer of complication, Dean Reese, a serial killer who kills anyone he thinks is a threat to Freida, is back.
